Problems solved by technology

The use of grouting protection has the following disadvantages: 1. The grouting is not full, and the steel bars cannot be effectively protected; 2. The phenomenon of grouting occurs, which leads to an increase in the amount of grouting; 3. The work efficiency is low and the energy consumption is high; 4. Increase post-operation and maintenance costs

Embodiment 1

[0020] Such as figure 1 As shown, in this embodiment, a pipe joint splicing device for an assembled pipe gallery includes a connecting sleeve 4 and sealing rings 1 arranged at both ends of the connecting sleeve 4 .

[0021] When in use, install the pipe joints of the fabricated pipe gallery in place, install the splicing device between two adjacent pipe joints, align the connecting sleeve 4 with the grouting hole, and seal the sealing ring 1 closely with the concrete surface of the pipe gallery Fitting to produce a sealing effect, the steel bars or steel strands used for pulling are loaded into the grouting holes, and the steel bars or steel strands can pass through the connecting sleeve 4 . After the steel bars or steel strands are installed in place, the grouting holes are grouted. Since the seal ring 1 is sealed and connected with the concrete surface, the grout leakage can be avoided, thereby avoiding grout leakage, insufficient grouting, etc., and can effectively improve ...

Embodiment 2

[0025] On the basis of the above embodiments, in this embodiment, the connecting sleeve 4 is made of elastic material. The connecting sleeve made of elastic material has certain elasticity and can be compressed within a certain limit. The length of the connecting sleeve 4 is greater than the minimum distance between two adjacent grouting holes. When the connecting sleeve 4 is installed, the connecting sleeve 4 can be compressed between the two pipe joints. Elasticity, which can make the connecting sleeve 4 be pressed against the concrete end face of the pipe joint, and exert a certain pressure on the sealing ring 1, thereby effectively improving the stability and position accuracy of the connecting sleeve 4, and increasing the contact between the sealing ring 1 and the The connection strength and sealing performance of the concrete end face.

Embodiment 3

[0027] On the basis of the above embodiments, in this embodiment, several springs 3 connected between the two sealing rings 1 are provided on the outside of the connecting sleeve 4 . After the connecting sleeve 4 is installed in place, the spring 3 is in a compressed state, and the elasticity of the spring 3 can be used to apply an outward thrust to the two ends of the connecting sleeve 4, thereby compressing the end of the connecting sleeve 4 on the The concrete end face of the pipe joint can effectively improve the stability and position accuracy of the connecting sleeve 4 .

Abstract

The invention discloses a pipe joint splicing device, a splicing structure and a splicing method for an assembly type pipe gallery. The pipe joint splicing device comprises a plurality of prefabricated pipe joints and a plurality of splicing devices, wherein the plurality of splicing devices are arranged between every two adjacent pipe joints, a plurality of grouting holes are formed in the pipe joints, the grouting holes and the splicing devices are arranged in a one-to-one correspondence mode, sealing rings are connected with the ends of the grouting holes in a sealed mode, and the splicing devices comprise connecting sleeves and the sealing rings which are arranged on both ends of the connecting sleeves. The pipe joint splicing device has the beneficial effects that the splicing device is arranged behind two pipe joints in a sleeving mode, and both ends of the splicing device are in sealed connection with the two pipe joints correspondingly, so that grout leakage can be effectively prevented, the grouting quality is guaranteed, and the condition that grouting is not full due to leakage is avoided.

Description

technical field [0001] The invention relates to the technical field of pipe gallery construction, in particular to a pipe joint splicing device, a splicing structure and a splicing method of a prefabricated pipe gallery. Background technique [0002] At present, my country is vigorously promoting the prefabricated underground pipe gallery project. During the construction of the prefabricated pipe gallery, pipe joints will inevitably be spliced. Most of the splicing is carried out by prestressed splicing. Among them, prestressed steel strands are widely used. Wire or fine-rolled rebar will be protected by grouting in the later stage. The use of grouting protection has the following disadvantages: 1. The grouting is not full, and the steel bars cannot be effectively protected; 2. The phenomenon of grouting occurs due to grouting, which leads to an increase in the amount of grouting; 3. Low work efficiency and high energy consumption; 4. Increase post-operation and maintenance ...
